Operating Procedures
It is essential that the APS75 Underground Pulling Trailer be properly set up before
operation. Using the following procedure will allow the unit to be set up in a short
period of time and yield optimum performance.
A. POSITIONING THE TRAILER & LOWER BOOM
Position the APS75 Puller within an approximate boom arm reach of the
manhole or duct bank. After trailer is positioned, lower boom arm.
NOTE: It may be necessary to payout a small amount of winch line (releasing it
from the boom) first to allow the boom to be lowered. If so please refer to Steps
C and D before proceeding.
NOTE: When operating the APS75 on a new build site or on soft
ground you will need to block the front jacks to prevent them from
sinking. Pulling the arm down until the lift cylinders cross the arm's
pivot point could result in damage to the puller during the pulling
operation or when lifting the arm for transport. An optional a-frame or
manhole adapter can reduce or eliminate these concerns.
Remove the traveling pin and carefully
lower the boom. (Figure 1). Install jacks,
and use jacks to raise arm into desired
position. (Figure 2). Now that the boom
is in place, minor adjustments in the
puller’s position can be made if
necessary for optimum working
alignment. If using the Hydraulic Arm
Control option, turn Master Switch to
*ARM position. The control valve is
mounted below the Control Panel. The
left lever controls right/left position. The
right lever controls up/down position.
B. STABILIzE TRAILER
After the APS75 is properly positioned,
place wheel chocks to prevent trailer
movement.
